1. It lacks the strong ribbing seen on many brachiopods.

2. These brachiopods are preserved in a distinctive way.

3. Such V-shaped ribs are not found on brachiopods, which have never developed the capacity for burrowing.

4. Some brachiopods are smooth, but many became corrugated or ornamented with course or fine ribs.

5. There must have been many different ways for brachiopods to exploit their simple mode of life.

6. The part brachiopod genera and species are described as addendum in this paper.

7. Fossil brachiopod evolved toward smaller size and the abundance of coral is reduced, these changes are connected with shallow water and cold climate.sentencedict .com

8. However, brachiopod research focused on shallow-water limestone facies, fewer papers of brachiopod in deep-water were published.

9. Though their long history from the early Cambrian to the present different groups of articulate brachiopods rose to prominence only to decline.

10. Benxi Formation in Duijiugou, Jungar Banner, Inner Mongolia is described and the brachiopod fauna from the formation is carefully analysed.

11. Thus, this area shOuld belong to North China Region(otprovince )of the Old World Realm in respoct to reginalism of brachiopod zoogeography during lateEaly Devonian time.

12. The biota of Upper Carboniferous is dominated by fusulinid and secondly by brachiopod and coral with flourished fossil plants in the lower pail.

13. The main controlling factor of the distribution and mutual replacement of the brachiopod communities is relative sea-level change.
